DESCRIPTION (provided by applicant): Health literacy has emerged as a critically important factor in health outcomes. Although existing measures of health literacy have distinct advantages and have been useful in research and clinical practice, each has characteristics that reduce its usefulness with some populations. The core aim of this application will be to develop a new health literacy measure with content, linguistic, and psychometric properties that will make it more broadly useful for screening and diagnostic purposes in clinical and research populations. It will be administered using computer touch screen technology to make the measure easily administered and scored and readily accessible via computers or the Internet. During development the measure will be validated by assessing its relations to other measures and participants' health. The planned development process will use item response theory (IRT) methods to develop a measure that functions equivalently in both Spanish and English and with younger and older persons. Its content will be broadly based following the recommendations health literacy experts and include audio and video items to enhance the measure's interest and validity. The measure will be computer administered using touch screen technology so that when deployed it may be self-administered and scored. The measure will be developed in two phases. We will first generate approximately 200 candidate items by rationally creating items of various levels of difficulty within broad content areas related to health literacy based on the content areas described in the Institute of Medicine report on health literacy (Nielsen-Bohlman et al., 2004). Items will be generated in Spanish or English and then translated and back translated into and from each language to ensure that their content is equivalent in both languages. We will then pilot test these candidate items in Spanish and English with 75 persons from each language group across several age ranges, drawing on persons aged 18 years and older. Items will be qualitatively evaluated using participant feedback and quantitatively using nonparametric IRT methods Items will be selected from the larger item pool for testing with larger groups of 30 persons in each decade of age from the 20s to 80s in both Spanish and English, so that 60 persons in each decade will be involved in the second phase of scale development for a total of 420 persons. The measure will be validated by assessing its relations with currently-used measures of health literacy, cognitive and academic measures, and health status, health care-related quality of life, and utilization of healthcare services. The creation of an easily-administered measure of health literacy will further the goals of this program announcement that requests applications focused on improved measures of health literacy. The new measure will be readily deployed over the Web. Future development will allow the creation of a computerized adaptive measure of health literacy and integrated tailored information applications to improve health literacy. PUBLIC HEALTH RELEVANCE: Health literacy is a critically important public health problem but current measures of it are inadequate. The application to be developed in this application will address this problem by creating a computer-administered measure of health literacy that is useful across age and language groups and is cost-effective to use.

描述（由申请人提供）：健康素养已成为影响健康结果的一个至关重要的因素。虽然现有的卫生知识普及措施具有明显的优势，并在研究和临床实践中发挥了作用，但每一种措施都有其特点，使其对某些人群的有用性降低。该应用程序的核心目标是开发一种具有内容、语言和心理测量特性的新的健康素养测量方法，使其更广泛地用于临床和研究人群的筛查和诊断目的。它将使用计算机触摸屏技术进行管理，使该措施易于管理和评分，并易于通过计算机或互联网访问。在制定过程中，将通过评估该措施与其他措施和参与者健康的关系来验证该措施。计划的开发过程将使用项目反应理论（IRT）方法来开发一种测量方法，该测量方法在西班牙语和英语中以及在年轻人和老年人中都具有同等的功能。其内容将广泛遵循卫生知识普及专家的建议，并包括音频和视频项目，以提高该措施的趣味性和有效性。该测试将由电脑使用触摸屏技术进行管理，以便在部署时可以自行管理和评分。该措施将分两个阶段制定。我们将首先根据医学研究所关于健康素养的报告（Nielsen-Bohlman et al., 2004）中描述的内容领域，在与健康素养相关的广泛内容领域中合理地创建不同难度的项目，从而产生大约200个候选项目。项目将以西班牙语或英语生成，然后将其翻译成每种语言并从每种语言进行翻译，以确保其内容在两种语言中都是等效的。然后，我们将用西班牙语和英语对这些候选项目进行试点测试，测试对象是来自不同年龄段、不同语言组的75名18岁及以上的人。项目将使用参与者反馈进行定性评估，并使用非参数IRT方法进行定量评估，项目将从较大的项目池中选择，在20岁至80岁的每个十年中使用西班牙语和英语进行更大的30人组测试，因此每个十年中有60人将参与第二阶段的量表开发，共420人。将通过评估该措施与目前使用的卫生素养、认知和学术措施、健康状况、与卫生保健有关的生活质量和卫生保健服务利用等措施的关系来验证该措施。建立一种易于管理的卫生知识普及措施将进一步实现该方案公告的目标，该方案公告要求应用侧重于改进卫生知识普及措施。新的措施将很容易在网络上部署。未来的发展将允许建立一种计算机化的卫生知识普及适应措施和综合的定制信息应用程序，以提高卫生知识普及。
